CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
The present application does claim priority from provisional Indian patent application 202021037992 filed on 3rd September 2020.

TECHNICAL FIELD
The present subject matter described herein, in general, relates to a light assembly for an automobile. More particularly, the present subject matter relates to a taillight assembly with an improved optical design to provide a three dimensional (3D) like illumination.

BACKGROUND
Generally, a lighting system is provided in a vehicle as a means for illuminating especially during night-time driving and as a means for indicating various signals during driving. Among lighting systems of the vehicle which are installed for this purpose, rear lamps which are mounted at both rear edges of a vehicle body are components in which a brake light, a taillight, and a turn signal are combined. The taillight provides a safety aspect of the vehicle. These lamps show the rear edge of the vehicle to allow other drivers to appropriately anticipate the size and shape of the vehicle. In addition, they allow other vehicles to see the car in inclement weather such as rain or snow.
The rear lamp of the vehicle contributes increasingly to the design of the vehicle. The design of the rear lamp gives the vehicle a characteristic appearance. Lately, there has been a trend to improve the design of the taillight to provide a crystal-like illumination. In most prior art, this effect has been achieved by using a costly reflector or/and by using a sheet of holographic/lenticular films. These solutions are costly and are available only in high end version of the cars.
Thus, there is a need for a light assembly with an improved optical design to provide a crystal-like three-dimensional effect. The design should be low cost which can be incorporated to all vehicles across the automotive segment.
